The town of Skaneateles created rules that apply to nonconforming uses, structures, and lots. Existing nonconforming lots with impermeable surface coverage may be redeveloped by a special permit. The impermeable surface area must be reduced to the maximum extent possible to minimize the impact on streams, lakes, and groundwater. Measures to reduce the impermeable surface includes infiltration trenches, vegetated streams, and lake buffers. If the lot is within the Skaneateles Lake Watershed, the Planning Board Engineer shall also consult with the City of Syracuse Department of Water in making this determination. The applicant must bear the expenses for the mitigation.
